Abstract
In a relay device or the like in which a speed changes from a high speed to a low speed, a packet residence (packet transfer wait) occurs when a packet string in which packet intervals are shortened arrives. When a packet discard occurs before passing through the relay device or the like, a packet interval having been lengthened by the packet discard is shortened by the relay device or the like for transferring packets. When a packet discard occurs after passing through the relay device or the like, a packet interval having been lengthened by the packet discard remains unshortened for transferring packets. Therefore, by observing at terminals the packet discard and the packet interval on the occasion of the packet discard, whether the packet discard has occurred in the high speed section or the low speed section is specified.
